Docker Volume未挂载任何文件

Question

我正在尝试将源文件安装到位于/ var / dynamo的Docker目录中。我希望能够在本地运行Docker并在工作时使用本地文件。

使用运行命令：

docker run -v $(pwd):/var/dynamo -d -t -p 8001:8001 --name dynamo davesrepo/dynamo

与我的 Dockerfile

FROM python:3.5.1
WORKDIR /var/dynamo
RUN pip3 install tornado
EXPOSE 8001

但是，当我将bash放入容器docker exec -it dynamo /bin/bash并运行时，ls -la该目录 为空！

root@7d3d338891aa:/var/dynamo# ls -la
total 4
drwxr-xr-x  2 root root   40 Dec 29 03:37 .
drwxr-xr-x 24 root root 4096 Dec 29 03:36 ..

运行docker inspect dynamo显示目录已正确安装

Docker版本是1.9.1

Answer 1

Docker＆Virtualbox在将卷装载到/
Users目录之外时似乎出现了问题。解决此问题的唯一方法是删除docker机器映像，在Virtualbox中正确设置/ Users /
yourname目录为共享文件夹，然后创建一个新的docker机器映像。

解决此问题的步骤：

1. docker-machine stop dev
2. docker-machine rm dev
3. docker-machine create --driver virtualbox dev
4. eval "$(docker-machine env dev)"
5. docker build -t davesrepo/dynamo -f ./Dockerfile .
6. docker run -v $(pwd):/var/dynamo -d -t -p 8001:8001 --env-file ./dynamo.env --name dynamo davesrepo/dynamo
7. docker exec -it dynamo /bin/bash
8. ls

root@42f9e47fa2de:/var/dynamo# ls Dockerfile README.md __init__.py __pycache__ bin config.ini requirements.txt seed.sql tests

文件！
